Answer:
After simplifying ur ans comes out to be option a
The angle A with 85, 10x is a 1345
The slope-point form:
We have two points (4, 5) and (-3, -1). Substitute:
For point (4, 5):
For point (-3, -1):
Set up the equation so m<HCB + m<DCH = m<DCB
2x + 100 + 60 = x + 170
2x+ 160 = x +170
-x -x
x + 160 = 170
- 160 -160
x = 10
